Richard Jarecki was born in Germany and became an American physician, working as a doctor while pursuing his passion for roulette. His scientific training gave him the patience and analytical skills necessary to study roulette wheels systematically. Unlike gamblers who relied on hunches, Jarecki approached roulette as an empirical problem.
Throughout the 1960s and 1970s, Jarecki systematically attacked European casinos, particularly in Germany and Italy. He would spend weeks observing a wheel, recording thousands of results before placing his first bet. His painstaking analysis identified biased wheels that gave him consistent edges.
Jarecki's method required extraordinary patience. He would observe a wheel for extended periods, often weeks, recording every spin. Only when his data showed statistically significant bias would he begin betting. This scientific rigor separated him from gamblers who relied on intuition or short-term patterns.
Jarecki's success forced European casinos to take wheel bias seriously. They began rotating wheels between tables, retiring older equipment, and implementing other countermeasures. His documented wins proved that wheel bias exploitation could generate substantial, sustained profits.
Richard Jarecki accumulated over $1.2 million from European casinos—an enormous sum in that era. His success demonstrated that Jagger's 19th-century methods remained viable decades later. He was eventually banned from most European casinos, a testament to the threat he posed to their profits.
